- Mould is common in moist materials and food, such as fruit, bread, cheese and meat.

- Scientists make predictions about what will happen based on the evidence they already have.
Keywords

Common misconception
Pupils may think that mould is a type of plant because of its colour or the way it grows.
Explain that plants make their own food using photosynthesis and mould does not, so it cannot be a plant. Instead, it gets its nutrients from the organic matter that it is growing on. Also, unlike plants, mould does not need light to survive or grow.
